IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. L10,09?, dated September 29, 1863.

To all whom it may concern:

Be it known that I, BENJAMIN F. FIELD, of Sheboygan Falls, in the county of Sheboygan and State of Wisconsin, have invented a new and improved method of converting a common drill or other seeding-machine into an efcient cultivator; and AI do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon, of which- Figure l is a rear elevation of a seeding-drill with my improvement attached. Fig. 2 is a longitudinal vertical section ofthe same. Fig. 3 is a plan view of my drag-bar. Fig. 4 is a view of detached shovel.

My invention consists in attaching a cultivator-share to an ordinary drill-tooth, in order that the drill seeding-machines iu common use may be at small expense readily converted into efficient cultivators.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The seeding-drill is constructed in any ordinary or desirable manner.

Ot' the machine represented in my drawings, A is the hopper or seed-box. B B are the Wheels. Gis the axle; E, portions ofthe frame of the machine. F is the drivers seat. G is the lifting bar or crank by means of which the drills, Src., are elevated clear of the ground. H is the handle by which the lifting-bar is operated. I I are the drill-teeth. K K are the shares or shovels which I propose to attach to the drill-teeth I I. L' 7c are straps permanently secured to the share K for the purpose of inclosing the tooth I, and k It" are screws which hold the straps k and shares K in position. L L are independent revolving shields attached to certain of the drag-bars M M, when the machine is used as a cultivator, the purpose of which will hereinafter be more fully shown. N N are the pivots connecting the drag-bars to the drill-teeth. O O are holes through the front end of shank of the drill-tooth, through one of which a wooden pin is inserted, thereby giving the properinclination to the drill-tooth or cultivator. I? P are the cords or chains supporting the drill-teeth or cultivators.

The drag-bar lM is constructed in the following manner: Two strips of iron two inches wide by one-fourth of an inch thick are taken of the properlength, (see Fig.3;) next, apiece of inch-board ten or twelve inches wide at one end and as wide at the other end as the shank otthc drill-tooth is thick and some ten or fifteen inches shorter than the strips of iron, which are now screwed or otherwise securely fastened to the edge of the board, the iron projecting three or four inches beyond the Wide end of the board. The object of this arrangement is to make a Very rigid drag-bar, which at the sanne time shall be very light and cheap. The wide end of the drag-bar is pivoted in any desirable way to the front ofthe cultivator-frarne, so that the free end may have a vertical movement.

The operation of my invention is as follows: The share K, having been constructed With the straps L" of such size and form as will adapt it to the particular style of drill-tooth in question, is placed on said drill-tooth by slipping the tooth inside the straps k until the point of the tooth nearly coincides with the point ot' the share. The screw or bolt 7c is then put in its place, and the share thereby rmly secured, and the drill-tooth is converted into a cultivator. A portion of drill-teeth may be removed and the revolving shields put in their place, the shields being so placed as to run between the share and the row of plants cultivated, their object and office being to prevent clods and masses of earth being thrown by the share against or upon the youngplants, to their detriment. They may be so adjusted by shortening their chains or cords as to run at any desired height, and thereby allow more or less earth to be thrown around the roots of the plants.

In going to or from the field, or at any other time when it is desirable the cultivators should not operate, they may be raised clear of the ground by turning the lifting bar or crank Gr up into the position indicated by the red lines. This is accomplished by the driver on his seat by pulling the handle H by its upper end, or itl by a person on the ground, he takes hold of the lower handle. The handle H is kept in position by its attachment to the bar G (which is by any suitable method) and the guide lt through which it passes. When it is desired to cause the cultivators to operate, the motions of the handle H before spoken of are reversed and the cultivators or drill-teeth fall to the ground.

My invention is applicable to any drill seeding-machine in use, and will enable the farmer to convert his drill into an efeient cultivator at a cost of only a tenth or twelfth of the cost of an equally good and complete cultivator.

I make no claim upon the construction of the drag-bar M, that having been claimed in my former application filed 3d September, instant. Neither do I claim the lifting-bar G, that being in common use; but

What I do claim as my invention, and desire BENJAMIN F. FIELD.
